CHARLES F. ENGSTROM, OF S'l. CHARLES, ILLINOlS.

ALBUMMAND SEEE 'I S THERE FOR.

Specification of Letters Patent.

Application led October 26, 1908.

To all whom it 'may concern:

Be it known that I, CHARLES F. ENGsTnoM, a citizen of the United States,residing at St. Charles, in the county of Kane and State of Illinois,have invented a new and useful Improvement in Albums and SheetsTherefor, of which the following is a specification.

My invention relates to certain new and useful improvements in albumsand sheets therefor, and is fully described and eX- plained in thespecification and shown in the accompanying drawings, in which- Figure lis an elevation ot' a book incorporating a series of leaves madeaccording to my invention; Fig. 2 is an elevation of one of the leaves;and Fig. 3 is a section on the line 3 of Fig. 2.

Referrino to the drawings, A is a sheet of paper, cardioard, or othersuitable material. To this sheet are secured corner-gripping sheets B,B1 and B2, the corner-gripping sheet B is rectangular in form anddiagonally disposed on the sheet A in such position as to present fourdiagonal edges under which the corners of four cards or other objects tobe mounted can be thrust in the manner indicated. The cornergrippingsheets B1 are triangular in shape and half the size of thecorner-gripping sheets B, and are disposed toward the centers of theedges of the sheet Aso that each presents two diagonally disposed edgesto engage two corners of the cards or pictures to be mounted. Thecorner-gripping sheets B2 are also triangular in shape, each being ofhalf the size of the corner-gripping sheets B1 and each is arran ed soas to present one diagonally disposed edge to receive one corner of acard.

In assembling sheets of any desired size, corner-gripping sheets similarto the corner-gripping sheets B will be selected for all interiorcorner-mountings, those similar to the corner-gripping sheets B2 will beselected for the eXtreme corners of the sheets, and the others, like thecorner-gripping sheets B1 will be selected for the intermediate lateralcorner-mountin 's. The corner-gripping sheets are secure( to the sheet Aby means of paste applied in such spots or lmes as to leave the centralportions of the diagonally disposed edges free to receive thereunder thecorners to be fixed in position. After the corner-gripping sheetsPatented Feb. 16, 1909.

Serial No. 459,619.

C is placed thereover, the said mask-sheet being of the same size as thesheet A and having a series of rectangular openings of such size and sopositioned that each opening exposes at its corners the central portionsof the four adjacent corner-gripping sheets. The mask-sheet is made ofthe same thickness of material as it is intended shall be mounted on thesheet or is made thicker than the cards to be mounted. As a result, whena card is inserted in position by thrusting its corners under thecorner-gripping sheets it will lie flush with or beneath the level ofthe mask-sheet.

It will be evident that, if desired, two sides of the central sheets Acan be utilized for picture-mounting by securing on each side thecorner-gripping sheets and masksheets, and such is the preferred form ofconstruction illustrated in Fig. 3 although it will be obvious that,should 1t be considered desirable, one side only of the sheet may beutilized for mounting purposes.

Sheets of the form herein illustrated and described are desirablebecause of their simplicity, cheapness and convenience in use whetherused singly or bound in book form. When, however, they are bound in bookform they are more especially desirable by reason of the fact that thepictures or cards lie Hush with or below the level of the masksheets sothat when a book or album is filled with pictures or cards it is nothicker than it was before such filling took place. It is, therefore,possible to bind up a book in the manner shown in Fig. l by utilizing aseries of my improved sheets without inserting between the sheetsspacing devices at the hinge, such as is usually necessary in connectionwith scrap-books or other volumes intended to receive additionalinserted matter upon the pages.

I realize that considerable variation is possible in the details of thisconstruction without departing from the spirit of my invention, and I donot intend, therefore, to limit myself to the speciic form herein shownand described.

lVhat I claim as new and desire to secure by Letters Patent is z- 1. Thecombination with a main-sheet, of a niask-sheet supported thereon andproviding openings vin which the cards to be mounted can lie,gripping-sheets interposed have been placed in position, a mask-sheet ibetween the main-sheet and the maslesheet and having free portionsWithin the openings of the mask-sheet beneath Which, por

Y tions or" a card or picture can be thrust.

2. A book comprising,'in combination, a series of pages each or whichcomprises a main-sheet, a mask-sheet provided With openings in Which acard can lie, and gripping-sheets having free portions lying Within theopenings in the mask-sheet to receive portions of the card or picture.

3. rlhe combination With a main-sheet and a mask-sheet having a seriesof rectangular openings therein, ot' a series of diagonally disposedcorner-gripping sheets having portions confned between the main andmasksheets, and free intermediate portions crossing diagonally thecorners of the openings in the mask-sheet to receive thereunder thecorners of the articles to be mounted.

4L. A book comprising, in combination, a series of pages each of whichconsists of a main-sheet and a mask-sheet having rectangular openings,and a series of cornergripping sheets conned between the main andmask-sheets and having free diagonally disposed portions crossing thecorner of the openings in the mash-sheets to receive the articles to bemounted.

5. The combination With a main-sheet and a mask-sheet having a pluralityof rectangular openings, of a series of corner-gripping sheets coninedbetween the main and mask-sheets, the corner-gripping sheets being ofsuch form and so positioned that Where there are adjacent openings inthe mask-sheet each corner-gripping sheet spans corners of such adjacentmask-openings.

6. A picture-mounting sheet having, in combination, a main-sheet, amask-sheet having rectangular openings, an interior corner-grippingsheet diagonally disposed and overlapping the adjacent corners of themask-openings, and corner-gripping sheets for the remaining corners otthe openings.

7. In combination in a picture-mounting sheet, a main-sheet, amask-sheet having a series of rectangular openings, corner-grippingsheets for the medial, lateral corners, each triangular in form andoverlapping the adjacent corners of the corresponding mask-openings, andcorner-gripping sheets for the remaining mask-opening corners.

S. In combination, a main-sheet and a mask-sheet provided With a seriesof rectangular openings and a series of corner-gripping sheets, tlieinterior cornergripping sheet being rectangular in form Vand diagonallydisposed so as to span the corners or' four adjacent mask-openings, themedial, lateral corner-gripping sheets being triangular in form anddisposed to span the adjacent corners of tivo mask-openings, .and thecorner corner-gripping sheets being triangular in form ot' halt' thesize of the lastnamed corner-gripping sheets to span one corner each ofthe mask-openings.
